Morn/E POWER FOR CHURNS.

SPECIFICATION forming part of Letters Patent N 0. 417,104, datedDecember 10, 1889.

Application filed April 27, 1889. Serial No. 308,793. (No model.)

T0 to whom it may concern Be itknown that 1, CHARLES W. SLAGEL, acitizen of the United States, residing at Davenport, in the county ofThayer and State of Nebraska, have invented certain new and usefulImprovements in Motive Power for Churns; and I do hereby declare thefollowingto beafull, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to makeand use the same.

My invention has relation to churns, and has for its object to produce achurn which is very simple in construction, which can be operated byeither hand or motive power, in which the throw of the dashers employedcan be readily varied, if desired, and in which the frame supportingsaid dashers, as well as the means for operating the same, maybe readilyplaced in position upon the vessel or removed therefrom when the processof churning is completed.

My invention consists in the combinations of parts, as hereinafter fullydescribed, illustrated in the accompanying drawings, and pointed out inthe appended claims.

In the drawings, Figure 1 is a side elevation of my improved churn, thevessel being partly broken away to show the arrangement of the dashers;and Fig. 2 is a top plan View.

A indicates the vessel, which may be of any desired shape, though I prefer to make it cylindrical, as shown. Near the upper edge of said vessel,upon either side, is secured in any suitable manner a plate a, each ofwhich is provided with two rectangular openings (0', for a purposepresently described. For supporting the dashers, as well as the meansfor operating the same, I employ a frame B, which is preferablyconstructed of iron, in order that the same may be durable and notliable to warp from moisture, the. It consists of the four uprights Z),connected at top and bottom by the longitudinal girts Z) Z2respectively, and the transverse pieces D The lower ends of the uprightsform feet which, when said frame is supported in position upon the upperedge of the vessel A, fit within the rectangular openings to in theplates or, and are thereby held firmly in place.

C 0 indicate the dashers that I employ,

which are, as ordinarily made, flat, and are provided at. their upperedges with pins 0, which pass through guide openings or slots 0" in thelongitudinal girts b of the frame.

In the operation of the churn it is my intention to impart asimultaneous oscillatory movement to the dashers in opposite'directions.The range of movement that I prefer to impart to each of said dashers issuch that the are that they describe will be equal to about one-fourthof the circle. I have, however, provided means whereby the range ofmovement of either or both ofsaid dashers may be readily varied, ifdesired, and will hereinafter appear.

For operating the dashers in the above-described manner, I employ thefollowing means: Rigidly mounted upon a transverse shaft (1, having itsbearings in the upper piece I) of the frame, is a gear-wheel D, whichmeshes with a pinion E on a transverse shaft 6, also having its bearingsin said pieces I), said shaft also carrying a fiy-wheel F.

The means for operating the dashers C and C from the shaft 6 are locatedupon opposite sides of the frame B and are identical in arrangement andoperation. Upon each end of the shaft 6 a crankf is mounted, upon apin fof which is pivoted one end of a rod f, the other end being pivoted upona pinf projecting from the upper end of a rock-lever G, pivoted upon apivot g.

H II are levers, one end of each of which is forked at II to embrace thelower ends of the levers G G, and are pivoted upon pins g, while theiropposite ends are pivoted upon pins g of the crank-arms I I, which arerigidly secured to the pins 0 on the dashers .0 and O.

In order that the dashers may be oscillated in reverse directions withrespect to each other, the cranks f f upon the ends of the shaft e will.be oppositely located thereon with respect to each other, as will beunderstood, as is plainly shown in Fig. 2.

The shaft (1 may be operated by hand, for which purpose I provide thehandle J, or by power, in which case I mount a belt-pulley uponsaid'shaft, as will be understood.

For varying the throw of the lower end of either or both of therock-levers G, and consequently the throw of the dashers, I provide saidlever with a series of openings 71, and make the pivot g removable, sothat by passing the pivot 9 through the different openings the aboveobject is accomplished.

It Will be seen that in the operation of the machine the revolution ofthe shaft 6 will, through the media of the cranks f and rods f rock thelevers G, and the latter will, through the media of the levers II andcrank I, cause the dashers to be oscillated simultaneously in oppositedirections with relation to each other.

I clain1 1. In a churn, the combination, with the cylindrical vessel A,having secured upon its upper edge the plates (0 a, provided withrectangular openings a, designed to receive and support the frame 13, ofthe transverse shaft 6, journaled in hearings in said frame and carryinga fly-Wheel F, and a gear-Wheel l1, meshing with a like wheel D on thetransverse shaft d, the cranks ff on each end of the shaft 6, the rods fleversGl'I, and cranks I I, arranged on opposite sides of the frame forimparting motion to the dashers C and C, substantially as described.

2. In a churn, the combination, with the cylindrical vessel A, havingsecured upon its upper edge the plates to a, provided with rectangularopenings a, designed to receive and support the frame B, of thetransverse shaft 6, journaled in bearings in said frame and carrying afly-wheel F, said shaft having upon its ends cranks ff, the pivotedlevers G G rovided with a series of o enin 's h for regulating the throwof the dashers, the pins 9, the rods f connecting the upper ends of thelevers G G with the cranks ff, and the adjustable levers H II, pivotedto the lower ends of the levers G G, and connected at their oppositeends to the cranks I I on the dashershafts, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
